System Description" .
3. Perform the preliminary check, Refer to BL-169, "
Preliminary Check"
4. According to the trouble diagnosis chart, repair or replace the cause of the malfunction. Refer to BL-169,
"Trouble Diagnosis Chart by Symptom" .
5. Does back door auto closure system operate normally? If Yes, GO TO 6, If No, GO TO 4.
6. INSPECTION END
Preliminary CheckNIS001OR
Remove the fuse No.18 for the back door closure with the back door closure inactive.
Check that the back door can be open / close normally.
CAUTION:
It is judged it is abnormal, discontinues closure operation, and drive lever returns to a neutral position
if not becoming full-latch within about three seconds after half-latch.
When this operation is done continuously three times, both back door closure and back door opener
switch are not operated because the function of back door closure is stopped.
Thing to reset power supply by pulling out and opening fuse in that case.
